[PATCH -perfbook v2] memorder: Shrink ifthen.pdf in -1c and -eb builds

ifthen.pdf is tall and using \columnwidth makes it exceed paper
height in -1c and -eb builds.

.5\onecolumntextwidth (defined in preamble) gives reasonable size
figures in all layouts.

v1 -> v2:
    Use \onecolumntextwidth for smaller figure in -2c builds.

Paul, this is a minimal change for fixing gitlab-ci error [1].

Figures 15.1 and 15.2 look unnecessarily large in -2c builds.
I'll tweak those figures as a followup change.

        Thanks, Akira
